Tiger horse

A somewhat adorable creature that haunts heavily traumatized minds. In one episode, a tiger horse finds its way into Dororo's mind and can only be defeated with things from his memories. Another also appears in episode 122, blocking the door out of the room in which Keroro watches a cursed DVD, where it appears in a manner similar to the Ring movies.

The Tiger horses' name is a direct pun on the Japanese for "trauma", トラウマ (torauma), which can be interpreted as "tiger" (tora) and "horse" (uma). Its appearance is based on Sadako Yamamura, the titular antagonist of Ring movies.
